Hello,
According to Session 228 of WWDC 2017 "Making Great SiriKit Experiences" I should be able to authenticate a user with Touch ID from within a Siri Extension.
I've been battling this for a while, but when I call -[LAContext evaluatePolicy:localizedReason:reply:] from withing the handle method I always get the same error on the callback:
"Error Domain=com.apple.LocalAuthentication Code=-1004 "User interaction is required." UserInfo={NSLocalizedDescription=User interaction is required.}"
I'm pretty much doing the same thing presented in that session…
What am I missing?
